smoothened receptor

SANT-1 directly binds to Smoothened (Smo) receptor (Kd: 1.2 nM) and inhibits Smo agonist effects (IC50: 20 nM).

SAG (Smoothened Agonist) is a Smo receptor agonist (EC50=3 nM) that is cell-permeable and selective. SAG regulates Smo activity by binding directly to the Smo helix and can activate the Hedgehog signaling pathway.

MRT-10 is a Smoothened (Smo) receptor antagonist.

Smoothened (Smo) receptor agonist

Taladegib (LY2940680) is an orally bioavailable small molecule antagonist of the Hedgehog (Hh)-ligand cell surface receptor smoothened (Smo) with potential antineoplastic activity.

DY131 (DY-131) is a novel selective agonist of ERRβ and ERRγ.

S1PL-IN-31 is a dual-function chemical compound acting as an inhibitor of sphingosine-1-phosphate (S1P) lyase with an IC50 value of 210 nM and as an antagonist of the Smoothened (Smo) receptor with an IC50 of 440 nM. Demonstrating therapeutic potential, this compound, at a dosage of 2 mg/kg per day, effectively mitigates cervical and thoracic lymphocyte infiltration and neuromuscular weakness in rats suffering from experimental autoimmune encephalomyelitis (EAE), a condition triggered by the MOG29-152 peptide from myelin oligodendrocyte glycoprotein. Additionally, it significantly decreases the total lymphocyte count, including reductions in subsets of CD4+ T cells, CD8+ T cells, and B cells. At a higher dosage of 100 mg/kg, S1PL-IN-31 elevates S1P levels within the heart and lymph nodes, while doses of 3 and 10 mg/kg per day notably lower heart rates in female rats, showcasing its multifaceted biological impacts and potential for clinical application.

Hh-Ag1.5 (SAG-1.5) is a potent Hedgehog (Hh) agonist (EC50: 1 nM) and Smoothened (Smo) receptor agonist, with an EC50 of 1 nM and Ki values between 0.5 and 2.3 nM for Smo. Hh-Ag1.5-mediated reprogramming breaks the quiescent state of non-injured hepatic stem cells and thus rescues liver failure. Hh-Ag1.5 induced differentiation of hiPSCs into skin precursor cells, spinal motor neurons and spinal sensory neurons.

MRT-83 (hydrochloride) is a potent antagonist of the Smoothened (Smo) receptor, effectively inhibiting the Hedgehog (Hh) signaling pathway and BODIPY-cyclopamine binding to human Smo. With its potential applications in the study of cancer disease, MRT-83 (hydrochloride) demonstrates promising prospects for research purposes.

Smoothened (SMO) is a GPCR-like receptor which, with Patched, mediates hedgehog signaling to regulate gene expression through the Gli transcription factors. 20(S)-hydroxy Cholesterol (20(S)-OHC) is an oxysterol which binds SMO and activates hedgehog signaling (EC50 = 3 μM), and this activation is selective for the nat-20(S)-OHC enantiomer. Nat-20(S)-OHC synergizes with the SMO agonist SAG, suggesting an allosteric effect. Nat-20(S)-yne is a form of nat-20(S)-OHC with a terminal alkyne group, which can be used in linking reactions known as click chemistry. Click chemistry involves highly dependable and specific azide-alkyne bioconjugation reactions and can be used to capture or immobilize bioactive molecules. Thus, nat-20(S)-yne has been conjugated with magnetic beads to demonstrate that nat-20(S)-OHC directly binds SMO.

M 25 is a Smoothened (Smo) receptor antagonist.

SAG dihydrochloride, a powerful agonist of the Smoothened (Smo) receptor (EC 50 = 3 nM; Kd = 59 nM), effectively activates the Hedgehog signaling pathway. It also negates the effects of Cyclopamine inhibition on Smo.

MRT-92 is a potent and selective Smoothened (Smo) receptor inhibitor. MRT-92 displays subnanomolar antagonist activity against Smo in various Hh cell-based assays. MRT-92 inhibits rodent cerebellar granule cell proliferation induced by Hh pathway activation through pharmacologic (half maximal inhibitory concentration [IC50] = 0.4 nM) or genetic manipulation. Smo is the target of anticancer drugs that bind to a long and narrow cavity in the 7-transmembrane (7TM) domain.

(Rac)-SAG, an isoform of SAG, is a potent Smoothened (Smo) receptor agonist (EC₅₀ = 3 nM; Kd = 59 nM) that activates the Hedgehog signaling pathway and counteracts Cyclopamine's inhibition of Smo [1] [2] [3].

LEQ506, also known as NPV-LEQ506, is an orally bioavailable small-molecule Smoothened (Smo) antagonist with potential antineoplastic activity. Smoothened antagonist LEQ506 selectively binds to the Hedgehog (Hh)-ligand cell surface receptor Smo, which may result in the suppression of the Hh signaling pathway, thereby inhibiting tumor cell growth.
